Firstly - I'm not 100% sure about communities. Aside from occasional posts on RPG.net, this would be the place to find Maelstrom posts. Of course, community can arise anywhere if enough fans come together to discuss the same topic, so feel free to spark something off yourself!

On the matter of online tools or apps, what sort of thing would you benefit from in running or playing Maelstrom? Given the pretty simple nature of the game system - what might an app bring to the table to make the game even more manageable?
